So I got working 10.4 in PearPC. I transfer files by TransMac. Works Fine,no problems.But I want network on it. Any chances to configure network connection on PPC?Im using WiFi. And my network card is Atheros AR5005G.

There's a thread in here where we tried to get the OpenVPN tunnel solution working with the OS X build of PearPC. I wasn't able to do it; I also wasn't able to get the Windows version of PearPC to do it inside a wrapper under OS X. But if you can figure it out, it's using Tun/Tap networking via an OpenVPN setup on Windows, and something similar would be needed on OS X.
